DUST COLLECTORV AND CONTROLLER FORhASII RECEPTACLES.

Application led April 24, 1924.. Serial No. 708,729.

This invention relates to certain new and useful improvements in dust collectors and controllers for ash receptacles wherein a device associated with an ash receptacle and having a pipe connection with a chimney or ue is constructed to permit the introduction of ashes therein for deposit in the receptacle with the dust passing upwardly :trom the receptacle and dust collector or device for discharge into the flue.

Another object of the invention is to provide a dust collector in the form of a hood or casing associated with anl ash receptacle and having a door therein for the introduction of ashesV with the bottom of the'hood or `receptacle constructed in a manner to accommodate the same for ash receptacles of diiferent sizes and insuring proper discharge of the ashes thru the collector into the receptacle.

Vith the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists ot' the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawings and claimed.

In the drawings, wherein like reference characters designate corresponding parts throughout the several views,

Figure 1 is a side elevational view, partlv broken away and shown in sect-ion of a dust collector for ash receptacles constructed in accordance with the present invention, the collector being illustrated as associated with an ash receptacle and a chimney or flue and shown in its elevated position by dotted lines spaced above the ash receptacle.

Figure 2 is a detail sectional view of the collector supported upon the upper end of an ash receptacle and showing the conical bottom thereof with the central opening to accommodate the mounting of the collector upon receptacles of different sizes,

Figure 3 is a horizontal sectional view taken on line III-III of Fig. 1 showing the door controlling the ash entrance to the collector moved inwardly to an open dotted line position,

Figure 4 is a front elevational view of a modified form of collector wherein the same is of casing construction for entirely enclosing an ash receptacle,

Figure 5 is a vertical cross-sectional view taken on line V-V of Fig. 4 showing the conical partition with the central opening' formed in the collector casing above the ash receptacle,

Figure 6 is a. horizontal sectional view taken on line VI-VI ot' F ig. 4 showing the door controlling the ash entrance to the casing moved inwardly and illustrated by dotted lines, and

Figure 7 is a top plan view of the collector casing shown in Fig. 4, the door for the collector casing being illustrated by dotted lines in an open position to permit placement of the ash receptacle.

Referring moreV in detail to the accompanying drawings, and particularly to Figs. 1 to 3 wherein a preferred form of the invention is illustrated, there is shown a dust collector for ash receptacles that is vert-ically shiftable to permit the disposition of an ash receptacle therebeneath with the collector lowered upon the open upper end of the receptacle and with a telescopic pipe connection between the collector and an outlet chimney or flue. The collector embodies a hood 1 open at its lower end as shown in f4 Fig. 2 and having a conical upper wall 2 terminating in a central vertical pipe section 3. The hood 1 carries a false bottom 4 ot inverted frusto-conical formation having a central opening 5 at its lower end, the false bottom 4 being spaced upwardly from the lower end of the hood to accommodate the mounting of the hood upon the open upper end of a receptacle R as shown in Fig. 2 with the false bottom 4 resting upon the upper end of the receptacle to be supported. thereby and with the lower end of the hood enclosing and spaced from the upper end of the receptacle. W'ith a hood and false bottom of this character, a hoodvof standard construction may be associated with ash receptacles of dii'erent diameters or heights to form a substantially dust-sealed connection between the hood and receptacle.

The support for the hood 1 includes a plurality of cords 6 secured at their lower ends to clips 7 carried by the upper end of the hood l with the upper ends thereof attached to the ring 8. Another cable or rope 9 attached to the ring 8 passes over pulleys 10 t depending from the upper floor structure 11 and supporting variable weights 12 at the free end thereof as shown in Fig. l, the weight of the hood overcoming the weight 12 for automatically lowering upon the ash mounted upon the upper end thereof'as shown by full lines in Fig. 1, the hood 1 is provided with a door 13 having draft openings 14 and being hinged as at 15 inwardly of the door opening 16, provided in the side of the hood 1 above the false bottom 4@ A door handle in the form of an arm 17 issecured as at 18 to the outer side of the door 13 adjacent the hinged end thereof and a coil spring 19 secured at its opposite ends as at- 20 to the hood l overlies the arm 1T intermediate the ends thereof and engaging said arm normally to move the same in a direction toward the hood with a consequent closing of thedooi` 13.

An elbow pipe section 21 having relatively long legs as illustrated in Fig. 1 has the upper end of the pipe section 3 t-elescoping within one vertical leg thereof, the other leg f of the elbow pipe extending into the chimney or iue 22 for purposes of carrying oftl the dust originating in the receptacle R and the collector hood. The use of the dust collector for ash receptacles is believed to be obvious from the above detail description of the invention, it being noted that the door `13 is'opened when engaged by a shovel laden withvashes and said ashes are deposited upon the false bottom 4 to descend thru the opening 5 into the receptacle R. `When the shovel is withdrawn from the door opening 16, the spring 19 engaging the door arm 17 automatically closes the door and a current of air thru the collector and associated pipe sections is caused by the provision of the draft opening 4 in the door 13 with the dust conveyed upwardly through the hood, pipe section 3, the elbow 21 and chimney 22.

Another form of the invention is shown fin Figs. 4 to 7 wherein a casing completely cncloses anfash receptacle, the casing being permanently supported upon a floor and having a hinged door permitting the posi tioning of an ash receptacle therein. casing 23 is open at its lower end and rests upon the floor F while the upper wall 24 thereof has an elbow pipe connection 25 with the chimney or tlue 22. @ne side wall of the casing 23 is provided with a hinged door 26 extending over substantially the entire surface thereof withA the door 2G hinged to the easing at one of its edges as at 27. The upper end of the door 26 is provided with anash receiving opening 28 closed by an auxiliary door 29 hinged as at 30 to the door 26 and carrying an operating arm 31 that is secured thereto as at 32 tothe outer side thereof adjacent the hinged end of the auxiliary door 29. The casing 23 adjacent the upper end V.thereof and spaced slightly below the ash receiving vopening 28 in the door 26 is provided with a horizontal partition 33 having a central opening disposed above the receptacle R as shown in Fig. 5. in placing the receptacle within the casing 23, the door26 .is open and the receptacle passed therethrough into the casing. lVith the door 26 closed, ashes are delivered to the receptacle R through the door opening 2S by causing the auxiliary door 29 to be opened when engaged by a shovel. The ashes Afall upon the partition 33 and descend through the openingV 34 to the receptacle. 1When the shovel is withdrawn through the opening 28, the handle or arm 31 may be engaged by the shovel for closing the door 29. 1f desired, a spring may be associated with the door arm 31 andthe same will automatically close.

While there are herein shown and described the preferred embodiments of the present invention, it is nevertheless to be understood that minor changes may be made therein. without departing from the spirit and scope of the invention as claimed.

lv'vlhat is claimed as new is 1- 1. In a dust collector for ash receptacles, a cylindrical casing adapted to fit over an ash receptacle, a frusto-conical top wall, for the cylindrical casing, having a flue connection in the central portion thereof, a bottom inverted -truste-conical wall for the cylindrical casing having a Acentral Vopening adapted to center the ashes and dust in their passage into and out of the ash receptacle and a spring `closed doo associated witn the cylindrical casing for admitting ashes into the inverted frust-o-conicai wall and ash receptacle.

A2. In a dust collector for ash receptacles, a cylindrical casing adapted to fit over an ash receptacle, a spring closed door in the casing, a frusto-conical top wall closing the upper end of the cylindrical casing having a telescopic flue connectionv with the atmosphere, a. frnsto-conical bottoni wall for the casing, having. a central opening adapted toy center the dust and ashes, in their passage into and out of the ash receptacle, said frusto-conical bottom wall being positioned above the lower edge of the cylindrical casing to forni a skirt for the :ish receptacle, for guiding the casing in position when lowered on the ash receptacle and counter-balance mechanism for moving the cylindrical casing into and out of its operative' position.
